Abstract
Wood biomass charcoal loaded with calcium was produced and the effects of the conditions of calcium-loading and carbonization on the product properties were examined. Calcium on charcoal was mainly CaCO3. In addition, the effects of calcium loading onto charcoal were examined for the removal of phosphorus from an aqueous solution. The amount of phosphorus removed increased with calcium loading while the amount removed by charcoal without calcium loading were small. Calcium phosphate would be produced on charcoal by the reaction of calcium on charcoal with phosphorus in aqueous solution.
